How to build a USSD service here, test it without a phone, and put it on a short code.

1. 1 Getting started Make a flow, find your way around the workspace, and dial it on the built-in phone.
2. 2 Screens Menus, inputs, routers and endings, and how a caller moves between them.
3. 3 Variables and phrases Put a caller's answers, API data and reusable wording into what the phone shows.
4. 4 API calls and data Call your own systems from a flow, decide what happens next from the answer, and list choices from data.
5. 5 Testing Dial the flow on the built-in phone, read the checks, and keep scenarios that must always pass.
6. 6 Going live Publish a version, rehearse it on staging, and connect a short code.
7. 7 AI assistants Let an assistant such as Claude build, check and dial your flows through MCP.
